Carburetor – General Chainsaw Adjustment
Adjusting the carburettor involves adjusting the engine to the local conditions e.g. climate, altitude, fuel and type of two-stroke oil. The carburettor is equipped with three adjustment options.
L = Low speed jet
H = High speed jet
T = Idling adjustment screw
The L and H jets adjust the fuel flow to match the airflow that the throttle valve opening allows. Turning them clockwise makes the fuel/air mixture weaker (less fuel in relation to the amount of air) and turning them anti-clockwise makes the fuel/air mixture richer. A weak mixture increases the engine speed and a rich mixture decreases the engine speed. The T screw controls the throttle position when idling. Turning the T screw clockwise gives faster idling; turning it anti-clockwise lowers idling speed (see manual for complete guide).

The Husky 49 chainsaw was a basically a Partner chainsaw based design that was considered as very reliable in it’s time. Easy starting, and fairly quiet running. With the 49 chainsaw, there have been two 49’s in the series – the first one never went into series production as the 49, but resulted in what is now known as the 50 Rancher – the second one was a late 1990s saw, that basically was the 40/45, with a 48.7cc engine on it. If you come across one of these chainsaws at a barn auction, grab it! These Husqvarna 49 chainsaws are considered collectors saws now, demanding good prices when sold to the right person.
